Trying add chunk of data to a array

As I understand the code, the fact that ls is empty after the loop implies that either:

• The while loop body never executes
• The if body never executes; or
• z is empty in the assignment ls = [ls z];

You haven't shown us how the values of x or i or Nfft get set, so we can only make educated guesses about the specific cause.

I suggest that you single-step through the code using the debugger. At each line, check the values of the key variables and make sure that each one contains what you think it should.

Thank you so much for reaching out hope your doing well in this case x is a arrary = Columns 1 through 19 12 3 43 2 2 3 4 1 88 888 666 444 22 56 7 4 2 0 9 Columns 20 through 30 8 5 2 4 7 8 9 0 7 5 3, i = 1, win = 30

[AJ Woodson]

I think I know now why this might not work array is 30 and win 30 so no deal

[Steve Eddins]

Yep. The if-body never executes because i+win <= length(x) is never true.

[AJ Woodson]

So I just ran this with win 2 Nfft =3 now runs but it taking forever same x

Nvm sorry figured it out
